Recently, an inter-slice MT imaging using bSSFP has been
proposed as a new method for MT imaging. To advance the
inter-slice MT imaging to quantitative MT, we tested
feasibility of modulation of inter-slice frequency
offsets by changing RF duration and inter-slice gap.
Experimental results showed that MT images from
different offset frequencies could be acquired by
changing the RF duration and inter-slice gap, which was
demonstrated in phantom and in vivo brain. The proposed
technique can enable us to acquire MT images at multiple
offset frequencies within a reasonable scan time and
thus may be useful for quantitative MT.
